Top ends of the protruding monofilaments are provided with bumps formed by melting/softening and then cooling the protruding monofilaments.

The length and density of the protruding monofilaments are reasonably designed to make the protruding monofilaments well hook and lock with the carpet above. In addition, the protruding monofilaments touch soft, and the bumps are not prickly.
